# How do you solve 3s+2(5s-1)=56.50?

Nov 8, 2016

$s = 4.5$

#### Explanation:

Step 1) Expand the terms in parenthesis.
Step 2) Combine like terms
Step 3) Solve for $s$ while keeping the equation balanced

$3 s + 10 s - 2 = 56.50$

$\left(3 + 10\right) s - 2 = 56.50$

$13 s - 2 = 56.50$

$13 s - 2 + 2 = 56.50 + 2$

$13 s = 58.50$

$\frac{13 s}{13} = \frac{58.50}{13}$

$s = 4.5$
